What are the key differences between electric potential energy ( $U_e$ ) and electric potential (V)?

$U_e$ : Energy (Joules) | V: Energy per unit charge (Volts)

Compare the equations for Work ( $W$ ) and change in Electric Potential Energy ( $Delta U_e$ ).

$W = \int F cdot dr$ or $W = Fd\cos(\theta)$ | $W = -\Delta U_e$

For a point charge, what is the shape of equipotential lines?

Concentric circles centered on the charge.

What is the relationship between electric field lines and equipotential lines?

Electric field lines are always perpendicular to equipotential lines.

What is the effect of moving a charge along an equipotential line?

No work is done, and the electric potential energy remains constant.

What happens to the electric potential (V) as the distance (r) from a point charge approaches infinity?

The electric potential (V) approaches 0.

What is the effect of doing work by the electric field on a charge?

The electric potential energy of the charge decreases.

What is the effect of doing work against the electric field on a charge?

The electric potential energy of the charge increases.
